Summary
French surgeons have significantly advanced spinal surgery over 50 years, impacting biomechanics and techniques. This review highlights key French innovations in spinal alignment, scoliosis, trauma surgery, and emerging technologies like AI and robotics.
Area of Science:
- Spinal surgery
- Orthopedic innovation
- Biomechanical research
Background:
- French contributions to spinal surgery are extensive but under-documented.
- Impact on biomechanics, surgical techniques, and broader implications needs exploration.
Purpose of the Study:
- To review France's contributions to spinal physiology, deformity surgery, and stabilization.
- To outline future perspectives in spinal surgery.
Main Methods:
- Narrative review of historical and recent French innovations.
- Analysis of contributions to spinal alignment, scoliosis, trauma, and technology.
Main Results:
- Pioneering work in sagittal balance and spinal alignment (Stagnara, Duval-Beaupère, Legaye, Roussouly).
- Revolutionary scoliosis management (Cotrel, Dubousset) and trauma surgery advancements (Roy-Camille, Louis, et al.).
- Key technological innovations including EOS imaging, vertebroplasty, and robotic surgery.
Conclusions:
- France has been a major driver of spinal surgery advancements over five decades.
- Continued leadership in emerging fields like AI, robotics, and personalized spinal surgery is evident.
